From 5fccb1081844131fcc9065cf13d1b28a80e26c2d Mon Sep 17 00:00:00 2001 From: José Bollo Date: Thu, 12 Oct 2017 22:54:23 +0200 Subject: agl-users: Use UID for HOME directories and logins MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit While dealing with systemd as a launcher, it appeared a limitation. If the template argument of units is used to designate the user it can not be different that the UID as a number because systemd enforce XDG_RUNTIME_DIR to be /run/user/. Thus using UID is the way to go to use template mechanic of systemd and use systemd as launcher. This is of importance because we don't expect systemd user to have full capabilities. Instead the framework will continue to leverage systemd launching mechanism but at a system level, with full capabilities but wil only allow user applications to deal with systemd --user. This impose to use UID as template parameters. The problem is then to set the user directory to the correct value knowing only the UID and using only possibilities of units. The only way is to have user home directories of the form /SOMETHING/ (where SOMETHING is merely "home"). This can be achieved either by setting a symbolic link (hard link tto directories are forbidden) or by simply using the scheme /home/UID in all cases. At the end, users within AGL will not receive nick names but will receive allocated UID. So, at the end, it is not a problem to use the regular naming scheme /home/UID, a scheme that will probably never be seen except by tools or experts. This patch implement this choice.
